• 📊 From 1990 to 2010, 1.7 billion people gained access to energy, driven by population growth and increasing demand for technology and comfort.
• 💰 Energy needs to be affordable, as otherwise it would be inaccessible to those who need it the most, impacting health, education, and industrialization.
• ⚡ Reliable energy is crucial to meet demands even during extreme conditions, such as droughts or power shortages.
• 🌿 Renewable energy sources are essential alternatives to fossil fuels, which are not only polluting but also finite.
• 💡 Among renewable sources, hydropower, solar, wind, and biomass are the most widely known, although there are others.
• ⚖️ All energy sources, including renewables, have pros and cons. It’s important to plan carefully, considering financial, societal, and environmental costs.
• 🌱 Sustainability involves economic, social, and environmental considerations, ensuring that renewable energy is truly sustainable and not just renewable.
• 🌎 The global consumption of fossil fuels decreased from 94.13% in 1960 to 80.92% in 2010, but fossil fuels remain dominant worldwide.
• 🇧🇷 Brazil stands out globally for its renewable energy share, with 43.5% of its energy coming from renewables, well above the global average.
• 🔋 A major contributor to Brazil's renewable energy comes from hydropower, which accounts for an impressive 68.1% of its electricity generation.
• 🌞 Solar power, particularly photovoltaic energy, has seen an incredible growth rate of 46.2% annually, making it a key renewable energy source.
• 🚀 Significant investments are being made globally to meet SDG 7, such as the installation of half a million solar panels per day worldwide in 2015.
